the tires thereof from wear. I attain these objects by means of an attachment composed of a series of metal calks connected together with links in the novel manner shown in Figures 1 and 2 of the drawings, the whole forming a metal coverin fitting over the tread part of the tire, w ich adjusts itself tothe contour and responds to the resiliency thereof; is connected with and held in-place by two metal hoops, one on either side of the tire; said hoops being provided with adjusters to increase or decrease the circumference thereof and hold the attachment in place. Tightening the adj usters s reads the calks laterally and tightens t em` around the circumference of the tire.

Fig. 1 of the drawings shows a perspec` tive view of .a section of the attachment in place over an automobile tire. Fig. 2 shows a section of the attachment spread out ilat, showing to better advantage the hoops, adjusters and side connections. Figs. 3 and 4 are detail views of a calk A. Fig. 5 is a detail view of a llink B. Figs. 6 and 8 are two views of the lug E to the hoop adjuster. Fig. 7 is a view of the bolt Fv 'to the hoop adjuster, and Figs. 9 and 10 are, views of' the side connection with the hoop'iD.

The calks A extend parallel with the tread of the tire and are arranged in sectionsof 8 calks to the section, divided into two groups of 4 calks each extending across the tread of the tte. In the center of the section the 8-calks7`r'e *connected to 2 links B, 4 calks to each link. -At the end of the section and whereit connects with the next section there are 8 calks connected to 3 links, 4 calks to the center link and 2 calks to each outside link. This order is maintained entirely each point where the sections come together and there are 3 links B in line laterall across the tread of the tire, a side strap connects the outside link B with the hoop D. The hoops D are provided with adjusters which comprise in their construction two lugs E E which are attached to the ends of the hoop wire D, a bolt F working through the lugs, a nut G and a key H through the head of the bolt F. This key H, which is shown to better advantagein Fig. 7, comes 1n contact with the hoop D, and prevents the bolt F from turning after it is adjusted. The shoulders of the nut G also come in contact with the hoop D, which holds the nut fromturning, so that the adjuster is locked at both ends.

I claim 1. A non-skid tire protector comprising a series of calks arranged in pairs side by side, said pairs being connectedend to end circumferentially around' saidV tire tread, certain of said connections connectingtogether all four of the adjacent ends of two pairs of said calks, whereby to prevent both circumferential and lateral separation, and certain of said -connections connecting the adjacent ends of the corresponding side calks, whereby to permit certain lateral spreading arond the circumference of the tire. AtY i apart of said calks, and means for securing pendent links, whereby to permit certain lateral spreading of said connected calks, and means for securing said protector around said tire.

3. In a tire protector of the character referred to, a series ofcalks arranged in groups of four abreast transversely of the tire tread, said groups being connected end to end cireumferentially of said tire, the two middle calks of each group being connected at one end to the ends of the two middle 2 l vf y 1,184,175

caks next adjacent, with the corresponding said tire, said connected outside calks can be ends of the outside calks of said group condrawn laterally to increase the tension, subnected to the ends of the adjacent outside stantially as described.

calks, While at their opposite ends said calks ALBERT GOODALL. are connected two and two to the corre- Witnesses: spending calks next adjacent, whereby at H. H. STAU'B, alternate connections circumferentially of `WM. BLACK.
